Material Resin Types

Acrylonitrile Provides heat stability, chemical resistance, and aging resistance.
Butadiene Provides low-temperature property retention, toughness, and impact
Styrene Adds luster, Rigidity, and processing ease.
The combination of the above items makes ABS a very tough material, especially around various acids and chemicals and where the product must withstand abuse. Dark colors will blanche out in moisture and high heat. Used in coffee mugs, oval trays, and compartment trays.


Acrylic Noted for its clarity, rigidity and scratch resistance. There are four types of Acrylic
Extrude Least chemical resistance of all Acrylics.
Poor chemical resistance. Used in sneeze guard shields.
Fair chemical resistance. Used in thermoformed product that will have food contact.
Good chemical resistance. Used in thermoformed product that will have food contact.
Acrylic has extremely high weatherability without yellowing or deterioration over long periods of time. It has poor chemical resistance at elevated temperatures.


Used where the weight and fell of ceramic is desired. Good in cold temperature use because of its rapid heat transfer, which is similar to ceramic, Has good high resistance (350F distortion temperature) and can be used in a microwave, but not recommended for foods with high sugar and grease contents. Excellent impact resistance, but surface hardness not as good as SAN.


Polycarbonate It has extremely high impact resistance and toughness, glass-like transparency and broad use temperature limits. It has good stain resistance, excellent surface, stiffness, and good chemical resistance. Is used in spoons, pebble bowls, pitchers, and Petal Mist dinnerware. This material is also used in some microwaveware. Its temperature use ranges from 0F to 275F.


High Density
Extremely chemical resistant, impact resistant, Not as rigid as SAN, used for material handling containers and storage containers where rough handling will occur. It is good in low-temperature applications (-50F). Used in bread and bun baskets, Bains Maries, and storage containers.
Low Density
Excellent chemical resistance, toughness, impact resistance, and stress crack resistance. Low-temperature use is -40oF.


It is more rigid and more scratch resistant than polyethylene.
It is very chemical resistant, durable and tough. Storage containers and Bains Maries have excellent contact clarity and have better low-temperature impact than Homopolylene. It is also used in Poly-tuf crocks for cold temperature use.
Same characteristic as other polypropylenes, but is slightly more flexible and has a much better impact. Used in dish racks.


High Heat
A rigid styrene that has good clarity. Used where rigidity and Polystyrene, clarity are desired, but chemical resistance is not required. Has higher heat High Heat resistance than general purpose styrene. Used in sugar caddies and tip trays. Is a brittle and low impact material similar to SAN.
High Impact 
 This is a polystyrene with rubber added to give greater impact resistance. It is not as rigid and brittle as SAN and is not chemical resistant
. Used in tortilla servers. Used in tortilla servers.
SAN  Used where chemical resistance, toughness, and gloss are required. Gives an excellent china-like appearance. Used for table top service where chemical resistance and appearance are important. Also, has good clarity but has a slightly bluish tint. Used in Continental and Crystalline pitchers, tumblers, Classic crocks, deli crooks, octagonal crocks and some mugs. BPA Free
Melamine  Excellent dinnerware materials with china-like appearance. Has the best scratch resistance of the dinnerware materials with china like appearance. Has the best scratch resistance of the dinnerware materials,  along with good chemical resistance, good impact resistance (will break) and broad-use temperature limits. Not recommended for microwave use.
Best material for high heat applications up to 400°F. Good rigidity, chemical resistance and excellent for microwave use. This is a strong material but may break if dropped on a hard surface. Can get a range of colors with little difference in cost. Black is a poor color and white
will yellow when exposed to temperatures near 400°F. Used in polyglass covers.
– Slurry
 Used in fiberglass trays. Very durable with good depth of color.
Good decoration capabilities.
